BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a portable terminal, programs for use in the terminal, a settlement apparatus that can perform data communication with the terminal, and a MERCHANDISING-information providing apparatus.

2. Description of the Related Art

Cellular telephones developed in recent years incorporate an external wireless interface that achieves wireless communication by using infrared rays, a non-contact IC card or the like. Settlement applications are now proposed, which enable a telephone user to pay charges and receive coupons by using the wireless interface.

Particularly, it is proposed that shops should electronically input receipts into the cellular telephone when the telephone user pays for whatever he or she has just bought. If the receipts are recorded in the form of electronic data, the user can have his or her household account book kept both electronically and automatically. This is advantageous to the telephone user. This is useful to the shops, too, because the expense involved in issuing paper receipts is saved. In view of this, it is well expected that the electronic-receipt issuing technology will soon come into use.

The amount of data that can be recorded on electronic receipts is almost limitless, unlike the amount of data recordable on conventional paper receipts. If shops issue electronic receipts, they can give the consumers far more merchandise and advertisement information than by issuing conventional paper receipts.

Jpn. Pat. Appln. KOKAI Publication No. 2005-141649, for example, discloses a technique of adding additional information to electronic receipts. In this technique, an electronic receipt with additional information is transferred to the purchaser's personal computer, and the personal computer records the information in the household account book. The purchaser can therefore review the additional information on the personal computer.

Thus, this technique enables the purchaser to review, on his or her personal computer, the additional information recorded on the electronic receipt. Most personal computers are unusable outdoors. Inevitably, consumers can access such value-added information only indoors. Assume that the merchandize bought is one for outdoor use and that the additional information (i.e., merchandise information) is instructions for solving problems with the merchandise. Then, the purchaser cannot access the information immediately while he or she is using the merchandise in the open.

BRIEF SUMMARY OF THE INVENTION

An object of the present invention is to provide a portable terminal on which the information contained in electronic receipts can be easily reviewed, even in the open, and a system that enables the user of the terminal to review the information.

According to an aspect of this invention, there is provided a portable terminal that comprises: a communications unit which communicates with an electronic-receipt server and a communications unit which communicates with a settlement-processing apparatus. On receiving simplified settlement data generated form settlement data and ID data for downloading electronic-receipt data from an electronic-receipt server, both from a settlement-processing apparatus, the portable terminal records the simplified settlement data in association with the ID data. The display unit of the portable terminal displays the simplified settlement data thus recorded.

The portable terminal downloads electronic-receipt data from the electronic-receipt server by using the ID data recorded in association with the simplified settlement data, when the input unit is operated, thereby commanding that the electronic receipt related to the simplified settlement data displayed by the display unit should be downloaded. The electronic-receipt data is recorded in the electronic-receipt recording unit. The display unit displays the electronic receipt on the basis the electronic-receipt data recorded in the electronic-receipt recording unit.

Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.

FIG. 9 is a flowchart that explains the sequence of major steps described in the electronic-settlement program P5 that is installed in the POS terminal 2. FIG. 10 is a flowchart that explains the sequence of major steps described in the electronic-receipt processing program P6 that is installed in the POS terminal 2.

How the portable terminal 8 performs electronic settlement will be explained with reference to FIG. 7 .

To make electronic settlement, the purchaser operates the input unit 18 provided on his or her portable terminal 8, activating the electronic settlement program P1. On the other hand, the cashier operates the POS terminal 2, registering the sales data concerning the merchandise the customer (i.e., purchaser) has bought, into the POS terminal 2. On registering the sales data, the cashier asks the purchaser to pay for the merchandise. So requested, the purchaser moves the portable terminal 8 toward the POS terminal 2, setting the communications interface 15 at a position close to the communications interface 26 of the POS terminal 2.

Since the electronic settlement program P1 has been activated, the CPU 11 of the portable terminal 8 monitors the communications interface 15 (Step S101). When the portable terminal 8 is moved near the POS terminal 2, the communications interface 15 starts communication with the communications interface 26 of the POS terminal 2. At this point, the CPU 11 sends a request for electronic settlement to the POS terminal 2 via the communications interface 15 (Step S102).

In response to this request, the POS terminal 2 performs electronic settlement with the portable terminal 8. When the electronic settlement is completed, the POS terminal 2 generates ID data for downloading electronic-receipt data from an electronic-receipt server 6 and simplified settlement data. The ID data and the simplified settlement data are transmitted from the communications interface 26 to the portable terminal 8. The ID data is information that is used to download the electronic receipt that has been uploaded from POS terminal 2 into the electronic-receipt server 6. The simplified settlement data is data extracted from the settlement data that is recorded on the electronic receipt.

In the portable terminal 8, the CPU 11 receives, via the communication interface 15, the ID data for downloading electronic-receipt data from an electronic-receipt server 6 and simplified settlement data transmitted from the POS terminal 2 (Step S103). The CPU 11 associates the ID data and the simplified settlement data with each other and then stores them into the non-contact IC card memory 27 (Step S104). Thereafter, the CPU 11 activates the electronic settlement program P2 (Step S105).

How the portable terminal 8 operates after the electronic-receipt processing program P2 has been activated will be explained, with reference to FIG. 8 .

In the portable terminal 8 with the electronic-receipt processing program P2 activated, the CPU 11 determines whether the non-contact IC card memory 16 stores simplified settlement data (Step S201). If the memory 16 stores the simplified settlement data, the CPU 11 makes the display unit 17 display the simplified settlement data (Step S202).

Next, the CPU 11 causes the display unit 17 to display a message asking the user whether the program P2 should be terminated and waits for an input from the user (Step S203). If the user inputs a command for terminating the program P2, the CPU 11 terminates the electronic-receipt processing program P2.

If the user inputs a command for keeping the activation of the program P2, the CPU 11 makes the display unit 17 display a message asking the user whether the electronic receipt corresponding to the simplified settlement data should be downloaded and then waits for an input from the user (Step S204).

If the user inputs a command for downloading the electronic receipt, the CPU 11 decodes the ID data stored in association with the simplified settlement data, thereby generating an URL that will be used to download the electronic receipt. Using the URL thus generated, the CPU 11 connects the public-network interface 14 to the Internet 5 (Step S205).

The URL represents the address of the electronic-receipt managing area 43 a provided in the electronic-receipt server 6, in which the electronic-receipt information has been uploaded from the POS terminal 2. The CPU 11 downloads the electronic-receipt information from the address (Step S206). The information thus downloaded is temporarily stored in the memory 12.

The CPU 11 analyzes the electronic-receipt information thus downloaded and makes the display unit 17 display the electronic receipt represented by this information (Step S207). The CPU 11 then waits for a confirmation from the user (Step S208).

When the user input a confirmation, the CPU 11 makes the display unit 17 display a message asking the user whether the electronic receipt should be stored in the portable terminal 8 (Step S209) and waits for an input from the user (Step S210). Upon receiving of the user input indicating that electronic receipt should be stored, the CPU records the electronic-receipt information in the recording unit 13 (Step S211). The CPU 11 then erases the electronic-receipt information from the temporary memory 12 (Step S212).

Next, the CPU 11 records the ID data and the simplified settlement data, both used to download the electronic receipt, in the recording unit 13 in association with the electronic-receipt information (Step S213). Alternatively, only the simplified settlement data may be recorded in association with the electronic-receipt information.

Thereafter, the CPU 11 erases the ID data and the simplified settlement data, both used to download the electronic receipt, from the non-contact IC card memory 16 (Step S214). The operation then returns to the first step.

How the POS terminal 2 operates after the electronic-receipt processing program P5 has been activated will be explained, with reference to FIG. 9 . In the POS terminal 2, the electronic-settlement program P5 is activated when the information about the merchandise the customer (i.e., user of the portable terminal 8) has bought.

In the POS terminal 2 with the electronic-settlement program P5 activated, the CPU 21 waits for a request for electronic settlement coming from the portable terminal 8 via the communications interface 26 (Step S301). A request for electronic settlement may come after the information concerning the merchandise has been registered. In this case, the CPU 21 performs the electronic settlement on the basis of the information concerning the merchandise (Step S302). Thus, the electronic settlement between the POS terminal 2 and the portable terminal 8 is completed (Step S303). Then, the CPU 21 activates the electronic-receipt processing program P6.

How the POS terminal 2, in which the electronic-receipt processing program P6 has been activated, operates will be explained, with reference to FIG. 10 .

In the POS terminal 2 with the electronic-receipt processing program P6 activated, the CPU 21 makes the customer display unit 30 display a message of, for example, “Please keep holding your portable terminal at the POS terminal 2” (Step S401). There is a time lag between the completion of the electronic settlement and the transmission of simplified settlement data to the portable terminal 8. Therefore, the ID data and the simplified settlement data, which is required to downloading the electronic receipt, cannot be transmitted if the user moves the portable terminal 8 away from the communications interface 26 of the POS terminal 2 immediately after the electronic settlement is accomplished. If these data items are not transmitted, the electronic receipt will not be transmitted to the electronic-receipt server 6. This is why the customer display unit 30 displays the message, telling the user not to move the portable terminal 8 away from the POS terminal 2.

While the display unit 30 is displaying the message, the CPU 21 performs a process for generating an electronic receipt and information items related to the receipt. More precisely, the CPU 21 extracts, from the merchandise-information managing area 23 a, the name and price of the merchandise registered at the electronic settlement, the merchandise-information accessing data and the like which should be recorded on the electronic receipt. Using these information items, the CPU 21 generates the electronic receipt (Step S402). Further, the CPU 21 extracts the data items, such as the date of settlement and the total amount paid for the merchandise, from the information items recorded on the electronic receipt, and generates simplified settlement data from the data items extracted (Step S403). Furthermore, the CPU 21 generates ID data which will be later used to download the electronic receipt from the electronic-receipt server 6 to the portable terminal 8 (Step S404).

At this point, the data on the electronic receipt and the simplified settlement data are formulated in such as Extensible Markup Language (XML) format as is shown in FIGS. 12 and 13 . On the electronic receipt, the merchandise-information accessing data is recorded as href=“http:// . . . ” in tag <merchandise> contained in the XML data (FIG. 12 ).

The CPU 21 connects the network interface 24 to the LAN and the Internet 5. The ID data for downloading the electronic receipt and the electronic-receipt information, thus generated, are transmitted from the POS terminal 2 to the electronic-receipt server 6 (Step S405). The CPU 21 further transmits the ID data for downloading the electronic receipt and the simplified settlement data to the portable terminal 8 via the communications interface 26 (Step S406).

On completing transmission of the ID data and the simplified settlement data to the portable terminal 8 (Step S407), the CPU 21 causes the display unit 30 to stop displaying the message (Step S408). The process of the electronic-receipt processing program P6 is thus completed.

How the user accesses the merchandise information on the electronic receipt when he or she reviews the electronic receipt displayed on the portable terminal 8 will be explained, with reference to FIG. 11 is a flowchart the sequence of major steps of the electronic-receipt reviewing program P3 installed in the portable terminal 8.

The user operates the input unit 18 provided on his or her portable terminal 8, thereby activating the electronic-receipt reviewing program P3.

In the portable terminal 8 with the electronic-receipt reviewing program P3 thus activated, the CPU 11 makes the display unit 17 to display a list of the simplified settlement data items concerning all electronic receipts stored in the recording unit 13 (Step S501). The CPU 11 then prompts the user to select at least one of the simplified settlement data items.

FIG. 14 shows some of the simplified settlement data items displayed on the display unit 17 at this point. As seen from FIG. 14 , the data items are displayed in the form of a list. The user operates the input unit 18, thus moving the cursor to any desired data item, on the screen of the display unit 17. The desired data item is thereby selected.

The CPU 11 determines whether the user has selected any simplified settlement data item (Step S502). If the user has selected a simplified settlement data item, the CPU 11 analyzes the XML data on the electronic receipt, which corresponds to the simplified settlement data selected and then makes the display unit 17 display the electronic receipt (Step S503).

FIG. 15 shows the data the display unit 17 displays at this time. As seen from FIG. 15 , the electronic receipt is displayed in the same layout as the corresponding paper receipt. The user can select any merchandise displayed on the display unit 17, by operating the input unit 18 and moving the cursor to the name of the merchandise displayed on the display unit 17.

The CPU 11 determines whether the user has selected any one of item of the merchandise recorded on the electronic receipt (Step S504). If any one item of merchandise has been selected, the CPU 11 makes the display unit 17 display the menu about the merchandise selected (Step S505). If the input is not concerned with selection of merchandise, the operation returns to Step S502.

After making the display unit 17 display the menu about the merchandise, the CPU 11 determines whether the user has selected “review merchandise information,” i.e., one of the menu items (Step S506). If “review merchandise information” has been selected, the CPU 11 extracts, from the data recorded on the electronic receipt, merchandise-information access data about the merchandise the user has selected (http://awinecompany.co.jp/for wine) (Step S507).

Thereafter, the CPU 11 activates the merchandise-information-site reviewing program P4. Using the merchandise-information accessing data, the CPU 11 accesses the merchandise-information site (i.e., the merchandise-information providing server 9) through the Internet 5 (Step S508).

If any item other than “review merchandise information” has been selected, the operation returns to Step S504.

The merchandise-information providing server 9 keeps activating the merchandise-information transmitting program P8 at all times and keeps waiting for an access from the portable terminal 8. In the merchandise-information providing server 9, the CPU 51 receives an access from the portable terminal 8. It then transmits the Web page of the merchandise information contained in the URL of the access, to the portable terminal 8. At this time the display unit 17 of the portable terminal 8 displays such data as shown in FIG. 16 . This operation is the same as one performed in the ordinary Web server, and will not de described here in detail.

In the network system of the configuration described above, the POS terminal 2 generates an electronic receipt showing the details of an electronic settlement when the POS terminal 2 at the transaction is settled with the customer at the shop 1. The electronic receipt thus generated is transmitted via the Internet 5 to the electronic-receipt server 6 and is published on Web.

At this time, the simplified settlement data based on the settlement data and the ID data for downloading the electronic receipt are transmitted from the POS terminal 2 to the portable terminal 8. When the customer operates the portable terminal 8, demanding that electronic receipt be downloaded, the electronic-receipt information is downloaded from the electronic-receipt server 6 into the portable terminal 8 in accordance with the ID data.

Thus, the customer can have the electronic receipt published on Web downloaded into the portable terminal 8 that incorporates a Web browser. He or she can therefore easily review the electronic receipt on the Web browser in the open, without necessity of going home and using the personal computer or the like at home.

The portable terminal 8 can access the merchandise-information providing server 9, by using the electronic receipt downloaded from the electronic-receipt server 6. The portable terminal 8 can then make the display unit 17 display the Web page about the merchandise, transmitted from the merchandise-information providing server 9.

Hence, the user can easily review the merchandise information in the Web page displayed on the display unit 17 of the portable terminal 8. This easy access to the information about the merchandise bought is very useful for the user, and also to the shops because the merchandise information helps to promote the sales.

FIG. 19 shows an example of the merchandise-information table T1 recorded in the merchandise-information managing area 23 a of the POS terminal 2. As shown in FIG. 19 , a purchase-site ID is stored as additional information about merchandise in the merchandise-information table T1, instead of the merchandise-information accessing data. The purchase-site ID is used to link the portable terminal 8 to a site on the Internet 5 so that the user may buy the merchandise corresponding to the ID.

In the second embodiment, the purchase-side ID is the data that links the portable terminal 8 to a site that the merchandise-providing server 90 provides. In the case shown in FIG. 19 , purchase-site ID “0512843” is recorded for merchandise name “wine 750 ml; price 9.81”.

FIG. 20 is a block diagram showing the major components of the merchandise-purchase server 90 included in the system according to the second embodiment. The merchandise-purchase server 90 comprises a CPU 61, a temporary memory 62, a recording unit 63, and a network interface 64. The CPU 61 constitutes a control unit. The temporary memory 62 can temporarily store data. The recording unit 63 stores various programs and various items of data. The network interface 64 can be connected to the Internet 5.

The recording unit 63 has a merchandise-information managing area 63 a where merchandize information is recorded, which is related to the merchandise items that are sold at the site. In the merchandise-information managing area 63 a, a merchandise-information transmitting program P12 and a merchandise-ordering program P13 are installed. The merchandise-information transmitting program P12 is used to transmit the merchandise information about any specific merchandise to the portable terminal 8. The merchandise-ordering program P13 is used to order any merchandise the user has ordered or the merchandise related to the merchandise the user has ordered.

FIG. 21 shows an example of the table T3 recorded in the merchandise-information managing area 63 a. As FIG. 21 shows, merchandise name “wine 750 ml” is recorded in the table T3, for the purchase-site ID “0512843.” Further, five items of information about merchandise related to this merchandise, i.e., “corkscrew,” “label-removing set,” “wine X 750 ml,” “wine Y 750 ml,” and “wine Z 750 ml,” are recorded in the in the table T3.

Dates are set, at which the related merchandise should preferably be purchased. In the present embodiment, the dates are set in accordance with the date at which the merchandise is most likely consumed. More specifically, the purchase date for “corkscrew” is set as “0 days later,” i.e., the same data as the merchandise “wine 750 ml” is purchases. The purchase date for “label-removing set” is set as “three days later,” because the wine is expected to be consumed three days after the wine is purchased. Similarly, the purchase dates for “wine X 750 ml,” “wine Y 750 ml,” and “wind Z, 750 ml” are set as “three days later,” “15 days later,” and “30 days later,” respectively, when “wine 750 ml,” “wine X 750 ml” and “wine Y 750 ml” are expected to be consumed. That is, when the user accesses to the information about specific merchandise, it is recommended that the merchandise related to the merchandise should be purchased at particular dates after the user has bought the merchandise.

FIG. 23 is a flowchart that explains the sequence of the major steps of the merchandise-information transmitting program P12 installed in the merchandise-purchase server 90. FIG. 24 is a flowchart that explains the sequence of the major steps of the merchandise-purchase-site reviewing program P11 installed in the portable terminal 8. FIG. 25 is a flowchart that explains the sequence of the major steps of the merchandise-ordering program P13 installed in the merchandise purchase server 90.

The electronic settlement program P1 and electronic-receipt processing program P2 installed in the portable terminal 8 and the electronic-settlement program P5 and electronic-receipt processing program P6 installed in the POS terminal 2 are identical in the sequence of major steps to those used in the first embodiment. Therefore, they will not be explained here in detail.

How the user accesses the merchandise information recorded on an electronic receipt by reviewing the electronic receipt on the portable terminal 8 will be explained, with reference to FIG. 22 .

The user operates the input unit 18 provided on his or her portable terminal 8, activating the electronic-receipt reviewing program P3.

Since the electronic-receipt reviewing program P3 has been activated, the CPU 11 of the portable terminal 8 makes the display unit 17 display a list of all simplified settlement data items about the electronic receipts thus far received and recorded in the recording unit 13 (Step S501). The CPU 11 then prompts the user to select at least one of the simplified settlement data items.

The CPU 11 determines whether the user has selected any simplified settlement data item (Step S502). If the user has selected a simplified settlement data item, the CPU 11 makes the display unit 17 displays the electronic receipt corresponding to the simplified settlement data selected (Step S503).

The CPU 11 then determines whether one of the items of merchandise recorded on the electronic receipt has been selected (Step S504). If any one of the items of merchandise has been selected, the CPU 11 makes the display unit 17 display the menu about the merchandise selected (Step S505). If the input is not concerned with selection of merchandise, the operation returns to Step S502.

After making the display unit 17 display the menu about the merchandise, the CPU 11 determines whether the user has selected “purchase related products,” i.e., one of the menu items (Step S506). If “purchase related products” has been selected, the CPU 11 extracts, from the data recorded on the electronic receipt, merchandise-purchase site ID and the date of purchasing the merchandise (Step S510). At this point, the place where the merchandise has been bought may be extracted, too.

Thereafter, the CPU 11 activates the merchandise-purchase-site reviewing program P11, accesses the merchandise-purchase site (i.e., merchandise purchase server 90) via the Internet 5 on the basis of the merchandise-purchase site ID, and transmits the date and time of purchasing the merchandise (Step S511). At the same time the date and time of purchasing the merchandise is transmitted, the data representing the site may be transmitted, too.

If any item other than “review merchandise information” is selected in the menu, the operation returns to Step S504.

The sequence of the major steps of the operation that the merchandise purchase server 90 performs when the user operates the portable terminal 8, thereby accessing the merchandise-purchase site, will be explained, with reference to FIG. 23 .

The merchandise purchase server 90 keeps activating the merchandise-information transmitting program P12 and keeps waiting for an access from the portable terminal 8 (Step S601). In the merchandise purchase server 90, the CPU 61 receives the purchase-site reviewing data and the date and time of purchasing the merchandise from the portable terminal 8 when the portable terminal 8 makes a demand for reviewing the purchase information (Step S602).

Next, the CPU 61 extracts, from the merchandise-information managing area 63 a of the recording unit 63, related merchandise recommended on the basis of the merchandise-purchase site ID contained in the purchase-site reviewing data and the date and time of purchasing the merchandise (Step S603). Assume the user of the portable terminal 8 has bought wine and accesses the merchandise purchase server 90 four days later. In this case, the CPU extracts “corkscrew,” “label-removing set,” and “wine X 750 ml,” as merchandise related to the wine.

Thereafter, the CPU 61 generates a purchase Web page for purchasing the related merchandise, on the basis of the data items extracted from the merchandise-information managing area 63 a (Step S604). The CPU 61 then transmits the Web page to the portable terminal 8 that has accessed the merchandise-purchase site (Step S605).

How the portable terminal 8 operates when the user orders the related merchandise will be explained, with reference to FIG. 24 .

The CPU 11 of the portable terminal 8 receives the Web page for purchasing the related merchandise, sent from the merchandise purchase server 90 (Step S701). The CPU 11 then makes the display unit 17 display the Web page (Step S702).

FIG. 27 shows another example of the information displayed by the display unit 17 of the portable terminal 8 at this point. This example of information is displayed when the user accesses “wine 750 ml” four days after he or she has bought the same merchandise, i.e., “wine 750 ml.” The merchandise related to “wine 750 ml,” i.e., “corkscrew,” “label-removing set,” and “wine X 750 ml,” are displayed. The user can place an order for these related items of merchandise by operating the input unit 18.

The user may operate the input unit 18, moving the cursor to any merchandise he or she would like to order and may push the OK button. Then, the CPU 11 of the portable terminal 8 determines that the user has selected the merchandise (Step S703). The CPU 11 then transmits ordered-merchandise information designating the merchandise selected, to the merchandise purchase server 90 (Step S704). If no merchandise is selected, the CPU 11 transmits data representing the end of process to the merchandise purchase server 90 (Step S705).

The sequence of the major steps of the operation the merchandise purchase server 90 performs when the user of the portable terminal 8 orders merchandise will be explained, with reference to FIG. 25 .

The merchandise purchase server 90 keeps activating the merchandise-ordering program P13 at all times and keeps waiting for an access from the portable terminal 8 (Step S801). Upon receiving an order for any merchandise from the portable terminal 8, the CPU 61 of the merchandise purchase server 90 places order for the merchandise to the seller who sells the merchandise (Step S802). After placing the order, the CPU 61 transmits a message to the portable terminal 8, telling that the order has been accepted (Step S803). (The message may read, for example, “The order for the merchandise has been duly accepted.”)

In the second embodiment, the portable terminal 8 can access the merchandise purchase server 90 on the basis of the data recorded on the electronic receipt downloaded from the electronic-receipt server 6. The portable terminal 8 further can acquire, from the merchandise purchase server 90, a Web page for ordering any merchandise and merchandise related thereto, and can cause the display unit 17 to display the Web page thus acquired. Using the Web page, the user can easily place an order for the merchandise displayed on the display unit 17.

Thus, it is easy for the user to access the merchandise related to the merchandise purchased. This is very useful for the user, and also to the shops because the merchandise information helps to promote the sales.
